Definitions

  • the present invention relates to an apparatus for automatically testing vehicles.
  • FIG. 1 is a diagram showing the arrangement of a conventional vehicle data transmitting system, such as may be applied to a railroad train.
  • reference numeral 1 designates a first vehicle having an operator's cab; 2 n through w 4 , second vehicles having no operator's cab, the first and second vehicles being connected to one another; 3, a central station mounted on the first vehicle for transmitting data; 4, terminal stations mounted on the second vehicles for receiving data from the central station 3; 5, optical transmission lines of optical fibers connecting the central station 3 and the terminal station 4 to one another; 6, control units mounted on the vehicles 1 and 2 n and connected to the central station 3 and the terminal stations 4, respectively, as shown in FIG. 1; 7, a control command unit connected to the central station 3; and 8, receptacles provided on the first and second vehicles 1 and 2 n and connected to the control units 6.
  • a control command output by the control command unit 7 is applied to the central station 3 and is then supplied through the transmission lines 5 to the terminal stations 4, and the control units 6 are operated by commands from the central station 3 and the respective terminal stations 4.
  • FIG. 2 In general, equipment mounted on the train is inspected with a test device as shown in FIG. 2, which is installed at a vehicle pool where trains are gathered.
  • reference numeral 9 designates a response signal generating unit; 10, a measuring unit, the units 9 and 10 forming a test executing unit 11; and 12, a plug connected to the test executing unit 11.
  • the plug 12 can be connected to the receptacles 8 of the vehicles 1 and 2 n .
  • reference numeral 13 designates a test controller connected to the test executing unit.
  • the plug 12 of the test device shown in FIG. 2 is connected to the receptacle 8 of a selected one of the vehicles so that the test executing unit 11 is connected to the control unit 6 of the vehicle.
  • the test controller 13 When so connected, the test controller 13 outputs a test command specifying a test item, and the response signal generating unit 9 supplies a response signal corresponding to the command to the control unit 6.
  • the control unit 6 is operated as required.
  • the operation signal of the control unit 6 is measured by the measuring unit 10, and the measurement signal is processed and recorded by the test controller 13.
  • the method is disadvantageous in that it takes a relatively long time to accomplish the test, and the received signal is affected by noise because the connecting line between the test executing unit 11 and the control unit 6 is relatively long; that is, it is impossible to automatically test the vehicles.
  • An object of the invention is to eliminate the above-described difficulties accompanying a conventional test device. More specifically, an object of the invention is to provide an automatic vehicle testing apparatus which allows the central station to operate in an automatic test mode, and in which a test controller installed at a test site is operated to cause the central station to operate in the automatic test mode, a response signal generating unit for operating a unit to be controlled and a monitoring unit for monitoring the operation thereof are connected to each terminal station and the respective unit to be controlled, and data provided in the automatic test mode is transmitted through the optical transmission lines.
  • FIG. 1 is an explanatory diagram showing the arrangement of a conventional vehicle data transmitting system

  • reference numeral 14 designates a central station connected to the control unit 6 and the control command unit 7, the central station 14 being operated in an automatic test mode when required; 15, terminal stations connected to the control units 6 and the central station 14; 16, a receptacle provided on the first vehicle 1 and connected to the central station 14; and 17, receptacles provided on the first and second vehicles 1 and 2 n , the receptacles 17 being connected to the central station 14, the terminal stations 15 and the control units 6.
  • the central station 14 and the terminal stations 15 are so designed that they transmit control data to their control units 6 only when they receive control commands from the respective control command unit 7.
  • a control command output by the control command unit 7 is applied through the central station 14 to the terminal stations 15 to operate the control units 6.
  • a train having the data transmitting system is sent to a vehicle pool provided with a test apparatus as shown in FIG. 4 where equipment on the vehicles is to be tested.
  • reference numeral 18 designates a test controller; 19, a plug connected to the test controller 18; 11, test executing units each having an associated signal generating unit 9 and a measuring unit 10 the same as the conventional test executing unit; and 20, plugs connected to respective ones of the test executing units 11. More specifically, each plug 20 is so connected to the respective test executing unit 11 that the associated signal generating unit 9 receives signals and the measuring unit 10 outputs signals.
  • the control command unit 7 is turned off and other necessary actions are taken to inhibit subsequent operation.
  • the plugs 19 and 20 are connected to the receptacles 16 and 17 of the vehicles 1 and 2 n , respectively, so that the central station 14 and the terminal stations 15 are connected to the test controller 18 and the test executing units 11.
  • the central station When, under this condition, test items and vehicles to be tested are specified for the test controller 18 and a test command is output, the central station, being placed in the automatic test mode, applies a test signal to the terminal stations 15 according to the test command, and the terminal stations 15 supply the test signal to the test executing units 11.
  • the control units 6 are operated by equivalent signals provided by the equivalent signal generating units 9 to apply operating signals to the measuring units 10.
  • the measuring units 10 process the operating signals to determine the appropriate operating conditions for the control units 6, and thereby apply the operating condition data to the respective terminal stations 15. This data is transmitted to the central station 14 and sent to the test controller 18. The data is displayed or recorded in the same manner for the test items in the test controller 18.
  • the control unit 6 on the first vehicle 1, which is connected to the central station 14, is tested by the latter as in the case of the control units 6 of the second vehicles 2 n .
  • FIG. 6 shows in more detail the structure of the central and terminal stations employed in the arrangement of FIG. 3.
  • a single optical fiber which forms the transmission lines 5 is coupled through electrooptical couplers 31 to a transmission control unit 32, the latter being coupled to a processing unit 33.
